Drawing processing is to do after the stamping, drawing can be based on decorative needs, made of ruled, chaos pattern, thread, ripple and spin and so on several.
Straight wire drawing refers to the aluminum plate surface with mechanical friction method to produce a straight line. It has the dual effect of brushing the surface of the aluminum plate and the surface of the decorative aluminum plate. Straight wire drawing with continuous wire and intermittent silk pattern two. Continuous wire pattern can be obtained by continuous horizontal friction (such as manual grinding or sandwiching the wire brush on the aluminum plate with a shredder) with a scourge or stainless steel brush. Change the diameter of stainless steel brush wire, you can get different thickness of the lines. Intermittent silk pattern is generally in the brush machine or rubbing machine processing system. Preparation of the principle: the use of two sets of the same rotation of the differential wheel, the group for the rapid rotation of the roller, the next group for the slow rotation of the roller, aluminum or aluminum alloy plate from the two sets of rollers through, Delicate intermittent ridge.
Ranling drawing is in the high-speed operation of the copper brush, so that the aluminum plate before and after the move friction obtained by a random, no obvious lines of matt silk pattern. This kind of processing, aluminum or aluminum alloy plate surface requirements are higher.
The corrugations are usually made on a brush machine or a rubbing machine. The use of the upper group of roller axial movement, in the aluminum or aluminum plate surface grinding, draw wave pattern.
Rotation is also known as optical rotation, is the use of cylindrical felt or stone nylon wheel mounted on the drilling machine, with kerosene to reconcile the oil, the aluminum or aluminum alloy plate surface rotation grinding obtained by a silk pattern. It is mostly used for decorative processing of circular signs and small decorative dials.
The thread is a small motor with a round felt on the shaft, which is fixed on the table with an angle of about 60 degrees from the edge of the table. In addition, a tray with a fixed aluminum plate is attached. A straight polyester film is used to limit the thread race. Using the rotation of the felt and the linear movement of the carriage, the thread of the same width is screwed on the surface of the aluminum plate.
Sandblasting is done in order to obtain the film light decoration or the surface of the fine reflection surface to meet the special design requirements such as gloss and softness. Uniform and appropriate sandblasting treatment, basically can also overcome the common defects on the surface of aluminum.
The appearance of parts, whether it is drawing or sandblasting, usually need to do surface oxidation. As for what kind of processing technology, should be related to the shape to consider a problem, the two processes can be obtained on the surface texture or different.
In addition there is a process and sandblasting close, but with a chemical corrosion method, commonly known as chemical rotten sand treatment or chemical sand surface corrosion, especially for aluminum surface treatment, the sand surface is much better than the spray Sand treatment. Chemical sand surface corrosion acid corrosion and alkaline corrosion. Different surface color and sand thickness can be obtained by different etching solvents and sanding agents.http://www.jiayunaluminium.com/
